Tec Week

April 21-27, 2024

Please join me for an epic two week, back to back wreck diving expedition to Truk Lagoon. On February 17th & 18th of 1944, United States Naval forces conducted the most daring carrier based aerial raid in history on the Japanese naval stronghold of Truk Lagoon in Micronesia. More than forty Japanese ships ended up at the bottom of the lagoon turning it into a modern day wreck diving mecca for sport divers the world over.  

I've been diving, filming & photographing the famed Japanese WWII wrecks since 2003 and am presently the captain of one of the finest luxury liveaboard dive vessels in the world, the M/V Odyssey. There is no safer, spacious and more luxurious a vessel to experience the wrecks of Truk from. I will be stepping aside as captain for these trips to focus all of my energy on the diving and
photo needs of the guests. I will utilize my 30 years of experience to make this dive expedition the most memorable. 

The first week of this dream itinerary is focused on diving the wrecks that have made Truk Lagoon famous. The Shinkoku, Hoki, Nippo, Fujikawa and the San Francisco Maru are all scheduled. The second week is dedicated certified tec diver who desires to dive the deeper less frequented wrecks such as the Amagisan, Aikoku and Shotan Maru (the San Francisco will also be on this itinerary). You can sign up for one or both of these trips. There are so many wrecks in Truk that you can dive two per day for two weeks and still not see them all!

Why not maximize your time on this side of the world and hit multiple top dive destinations with one airfare! Palau and Papua New Guinea are just the ticket. Both are adventurous world class dive locales and relatively easy to get to from Chuuk. I have lived and worked in Palau and know the destination well. PNG is not yet back on the itinerary but stay tuned. 

The Truk Odyssey 

 Since 1999, the Odyssey and her highly experienced crew have been taking avid divers in the lap of luxury to dive the wrecks of Truk Lagoon. The 133' vessel is tricked out to meet the most discerning divers needs. The luxury spacious staterooms with individual climate control will provide the perfect place to rest up between dives and get a good nights sleep. The delicious food served in the large dining room will not disappoint. Odyssey is a perfectly designed dive platform with everything the recreational and technical diver could ask for. Individual dive lockers, outdoor shower, rinse tanks and extra large camera table are but a few of the amenities on deck.  In addition, get truly spoiled with a diver lift from the water to the swim deck. Climb on and up you go. No exertion, no fuss. Great for divers with heavy gear or physical issues where climbing ladders is difficult. There are no details overlooked on the Odyssey.
